Unveiling the universe with emerging cosmological probes
(Springer, 2022)
The detection of the accelerated expansion of the Universe has been one of the major breakthroughs in modern cosmology. Several cosmological probes (Cosmic Microwave Background, Supernovae Type Ia, Baryon Acoustic Oscillations) ...
Impact of Rubin observatory cadence choices on supernovae photometric classification
(American Astronomical Society, 2023)
The Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) will discover an unprecedented
number of supernovae (SNe), making spectroscopic classification for all the events infeasible. LSST will thus rely
on ...
The fore ground transfer function for H I intensity mapping signal reconstruction: MeerKLASS and precision cosmology applications
(Oxford University Press, 2023)
Blind cleaning methods are currently the preferred strategy for handling foreground contamination in single-dish H I intensity mapping surv e ys. Despite the increasing sophistication of blind techniques, some signal loss ...
Hydra ii: Characterisation of Aegean, Caesar, profound, pybdsf, and selavy source finders
(Cambridge University Press, 2023)
We present a comparison between the performance of a selection of source finders using a new software
tool called Hydra. The companion paper, Paper I, introduced the Hydra tool and demonstrated its
performance using ...
Hydra I: An extensible multi-source-finder comparison and cataloguing tool
(Cambridge University Press, 2023)
The latest generation of radio surveys are now producing sky survey images containing many millions of radio sources. In this context it is highly desirable to understand the performance of radio image source finder (SF) ...
